After sources exclusively told us they were “officially dating,” Page Six has learned that she will no longer attend the upcoming Angel Ball with him after reports surfaced Wednesday that Salt Lake City police were searching for Mueller and her sons.

“He is not bringing her,” a source close to Roth said.

His soon-to-be ex-wife Noreen is “having a very difficult time getting divorced from him because they’re business partners,” a second source told us.

Police had been hunting for Mueller early Wednesday after they received a call that she was acting strangely with her kids in a Utah carwash parking lot.

The kids were deemed safe after a welfare check, but Mueller was checked into a hospital for a psychiatric evaluation, according to TMZ.

“She’s still struggling with her sobriety, but she genuinely tries very hard to keep it under control for the sake of her kids. She moved to Park City to get away from the craziness. She’s very sincere in wanting to be a good mom and to get through this,” a source close to Mueller said.
